Workers binding

Atualizado em Ver como Markdown

Use the Artifacts Workers binding to create, import, inspect, fork, and delete repos directly from your Worker. The Artifacts binding returns repo handles that allow repo-scoped operations such as token management and forking.

Review Namespaces first, then choose the namespace name you will bind here.

Configure the binding

Add the Artifacts binding to your Wrangler config file:

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "artifacts": [
    {
      "binding": "ARTIFACTS",
      "namespace": "default"
    }
  ]
}
[[artifacts]]
binding = "ARTIFACTS"
namespace = "default" # replace with your Artifacts namespace
# remote = true # optional: use the remote Artifacts service in local dev

After you run npx wrangler types, your Worker environment looks like this:

export interface Env {
	ARTIFACTS: Artifacts;
}

Wrangler generates the Artifacts type for consumers and binds it directly in your environment.

In named Wrangler environments, artifacts is non-inheritable. Repeat the binding in each environment where you need it.

At runtime, deployed Workers use the configured binding directly. For local Wrangler commands such as wrangler dev, wrangler deploy, or wrangler types, authenticate Wrangler first. For local OAuth authentication, refer to wrangler login. For CI or headless environments, refer to Running Wrangler in CI/CD.

Namespace methods

Use namespace methods on env.ARTIFACTS to create, list, inspect, import, or delete repos.

create(name, opts?)

  • name RepoName required
  • opts.readOnly boolean optional
  • opts.description string optional
  • opts.setDefaultBranch string optional
  • Returns Promise<ArtifactsCreateRepoResult>

create() returns repo metadata including name, remote, defaultBranch, and an initial token. Save these values if you need them later.

async function createRepo(artifacts) {
	const created = await artifacts.create("starter-repo", {
		description: "Repository for automation experiments",
		readOnly: false,
		setDefaultBranch: "main",
	});

	return {
		defaultBranch: created.defaultBranch,
		name: created.name,
		remote: created.remote,
		initialToken: created.token,
	};
}
async function createRepo(artifacts: Artifacts) {
	const created = await artifacts.create("starter-repo", {
		description: "Repository for automation experiments",
		readOnly: false,
		setDefaultBranch: "main",
	});

	return {
		defaultBranch: created.defaultBranch,
		name: created.name,
		remote: created.remote,
		initialToken: created.token,
	};
}

get(name)

  • name RepoName required
  • Returns Promise<ArtifactsRepo>
  • Throws if the repo does not exist or is not ready yet.

get() returns a handle to an existing repo. Use the handle to call async methods on the repo, such as createToken(), listTokens(), revokeToken(), and fork().

async function getRepoHandle(artifacts) {
	const repo = await artifacts.get("starter-repo");
	const token = await repo.createToken("read", 3600);
	return token;
}
async function getRepoHandle(artifacts: Artifacts) {
	const repo = await artifacts.get("starter-repo");
	const token = await repo.createToken("read", 3600);
	return token;
}

list(opts?)

  • opts.limit number optional
  • opts.cursor Cursor optional
  • Returns Promise<ArtifactsRepoListResult>
async function listRepos(artifacts) {
	const page = await artifacts.list({ limit: 10 });

	return {
		repos: page.repos.map((repo) => ({
			name: repo.name,
			status: repo.status,
		})),
		nextCursor: page.cursor ?? null,
	};
}
async function listRepos(artifacts: Artifacts) {
	const page = await artifacts.list({ limit: 10 });

	return {
		repos: page.repos.map((repo) => ({
			name: repo.name,
			status: repo.status,
		})),
		nextCursor: page.cursor ?? null,
	};
}

Each listed repo includes a status value of ready, importing, or forking.

import(params)

Import a repository from an external git remote.

  • params.source.url string required — HTTPS URL of the source repository.
  • params.source.branch string optional — Branch to import (defaults to the remote's default branch).
  • params.source.depth number optional — Shallow clone depth.
  • params.target.name RepoName required — Name for the imported repo.
  • params.target.opts.description string optional
  • params.target.opts.readOnly boolean optional
  • Returns Promise<ArtifactsCreateRepoResult>

import() returns repo metadata including name, remote, defaultBranch, and an initial token. Save the remote and name values if you need them later.

async function importFromGitHub(artifacts) {
	const imported = await artifacts.import({
		source: {
			url: "https://github.com/cloudflare/workers-sdk",
			branch: "main",
		},
		target: {
			name: "workers-sdk",
		},
	});

	return {
		name: imported.name,
		remote: imported.remote,
		token: imported.token,
	};
}
async function importFromGitHub(artifacts: Artifacts) {
	const imported = await artifacts.import({
		source: {
			url: "https://github.com/cloudflare/workers-sdk",
			branch: "main",
		},
		target: {
			name: "workers-sdk",
		},
	});

	return {
		name: imported.name,
		remote: imported.remote,
		token: imported.token,
	};
}

delete(name)

  • name RepoName required
  • Returns Promise<boolean>
async function deleteRepo(artifacts) {
	return artifacts.delete("starter-repo");
}
async function deleteRepo(artifacts: Artifacts) {
	return artifacts.delete("starter-repo");
}

Repo handle methods

Call await artifacts.get(name) to get a repo handle. Use the handle to call async methods on the repo.

createToken(scope?, ttl?)

  • scope "read" | "write" optional (default: "write")
  • ttl number optional (seconds)
  • Returns Promise<ArtifactsCreateTokenResult>
async function mintReadToken(artifacts) {
	const repo = await artifacts.get("starter-repo");
	return repo.createToken("read", 3600);
}
async function mintReadToken(artifacts: Artifacts) {
	const repo = await artifacts.get("starter-repo");
	return repo.createToken("read", 3600);
}

Unlike create() and import(), repo.createToken() returns a structured result with plaintext and expiresAt. The plaintext value is the Git token string.

listTokens()

  • Returns Promise<ArtifactsTokenListResult>
async function listRepoTokens(artifacts) {
	const repo = await artifacts.get("starter-repo");
	const result = await repo.listTokens();
	return {
		total: result.total,
		tokens: result.tokens,
	};
}
async function listRepoTokens(artifacts: Artifacts) {
	const repo = await artifacts.get("starter-repo");
	const result = await repo.listTokens();
	return {
		total: result.total,
		tokens: result.tokens,
	};
}

revokeToken(tokenOrId)

  • tokenOrId string required
  • Returns Promise<boolean>
async function revokeToken(artifacts, tokenOrId) {
	const repo = await artifacts.get("starter-repo");
	return repo.revokeToken(tokenOrId);
}
async function revokeToken(artifacts: Artifacts, tokenOrId: string) {
	const repo = await artifacts.get("starter-repo");
	return repo.revokeToken(tokenOrId);
}

fork(name, opts?)

  • name RepoName required
  • opts.description string optional
  • opts.readOnly boolean optional
  • opts.defaultBranchOnly boolean optional
  • Returns Promise<ArtifactsCreateRepoResult>

fork() returns metadata for the new repo. Save the remote and name values if you need them later.

async function forkRepo(artifacts) {
	const repo = await artifacts.get("starter-repo");
	const forked = await repo.fork("starter-repo-copy", {
		description: "Fork for testing",
		defaultBranchOnly: true,
		readOnly: false,
	});

	return forked.remote;
}
async function forkRepo(artifacts: Artifacts) {
	const repo = await artifacts.get("starter-repo");
	const forked = await repo.fork("starter-repo-copy", {
		description: "Fork for testing",
		defaultBranchOnly: true,
		readOnly: false,
	});

	return forked.remote;
}

log(opts?)

  • opts.ref string optional — Branch, tag, or commit hash.
  • opts.limit number optional
  • opts.offset number optional
  • Returns Promise<ArtifactsLogResult>
async function readCommitHistory(artifacts) {
	const repo = await artifacts.get("starter-repo");
	const history = await repo.log({ ref: "main", limit: 10 });
	return history;
}
async function readCommitHistory(artifacts: Artifacts) {
	const repo = await artifacts.get("starter-repo");
	const history = await repo.log({ ref: "main", limit: 10 });
	return history;
}

readCommit(hash)

  • hash string required — Commit SHA-1 hash.
  • Returns Promise<ArtifactsCommit>
async function readCommit(artifacts, hash) {
	const repo = await artifacts.get("starter-repo");
	return repo.readCommit(hash);
}
async function readCommit(artifacts: Artifacts, hash: string) {
	const repo = await artifacts.get("starter-repo");
	return repo.readCommit(hash);
}

readTree(hash)

  • hash string required — Tree SHA-1 hash.
  • Returns Promise<ArtifactsTree>
async function readTree(artifacts, hash) {
	const repo = await artifacts.get("starter-repo");
	return repo.readTree(hash);
}
async function readTree(artifacts: Artifacts, hash: string) {
	const repo = await artifacts.get("starter-repo");
	return repo.readTree(hash);
}

Worker example

This example combines the binding methods in one Worker route.

src/index.jsjs
export default {
	async fetch(request, env) {
		const url = new URL(request.url);

		if (request.method === "POST" && url.pathname === "/repos") {
			const created = await env.ARTIFACTS.create("starter-repo");
			return Response.json({
				name: created.name,
				remote: created.remote,
			});
		}

		if (request.method === "POST" && url.pathname === "/tokens") {
			const repo = await env.ARTIFACTS.get("starter-repo");
			const token = await repo.createToken("read", 3600);
			return Response.json(token);
		}

		return Response.json(
			{ message: "Use POST /repos or POST /tokens." },
			{ status: 404 },
		);
	},
};
src/index.tsts
interface Env {
	ARTIFACTS: Artifacts;
}

export default {
	async fetch(request: Request, env: Env): Promise<Response> {
		const url = new URL(request.url);

		if (request.method === "POST" && url.pathname === "/repos") {
			const created = await env.ARTIFACTS.create("starter-repo");
			return Response.json({
				name: created.name,
				remote: created.remote,
			});
		}

		if (request.method === "POST" && url.pathname === "/tokens") {
			const repo = await env.ARTIFACTS.get("starter-repo");
			const token = await repo.createToken("read", 3600);
			return Response.json(token);
		}

		return Response.json(
			{ message: "Use POST /repos or POST /tokens." },
			{ status: 404 },
		);
	},
} satisfies ExportedHandler<Env>;

Generated types

Run npx wrangler types in your own project and treat the generated worker-configuration.d.ts file as the source of truth for the Artifacts binding types in that environment.
